Digital Object Identifier (DOI)
A DOI is a unique, permanent alphanumeric string assigned to a digital document, providing a reliable link to the document online.
1Detailed Explanation
DOIs were introduced in 2000 to create persistent identifiers for digital content. A DOI begins with '10.' followed by the registrant code and suffix specific to the document: '10.1056/NEJMoa2034577'. DOIs never change, unlike URLs, making them ideal for citations. They are now required by most journals for all references. DOIs resolve to the document's landing page (publisher or CrossRef). Many journals display DOIs prominently on the article page. Use the DOI link format: 'https://doi.org/10.xxxx/xxxxx' for hyperlinks. The DOI system is managed by the International DOI Foundation. DOIs should be included in all references to journal articles, books, and reports.

3Why It Matters in Research
DOIs are essential for accurate citation in modern medical literature. Always include DOIs when available, as they improve citation linking and traceability.
